Impact of groins on beach morphology: a case study near Gopalpur Port, east coast of India. Gopalpur Port is being developed as an all-weather open seaport from a fair-weather port which has existed since 1987.

Port authorities are planning to construct a southern breakwater and a series of seven northern groins. Therefore, it is essential to assess the impacts of coastal structures on beach morphology and shoreline change in the present context and to predict future trends. To achieve this, a long-term observational programme has been conducted since May 2008. Observations include beach profile, shoreline change (berm position), littoral environment ...
